Re: Drives confirmed to be modifiable for one-pass flippy

Mitsumi/Newtronics D509V2: Takes a lot of filing and you'll probably have to move the stepper motor (which means realignment is necessary). Bypass circuit is easy to connect since "GND" and "TR00" are big, clearly marked solder pads on the PCB. The result seems to be sturdy enough.

Re: One-pass "flippy" disk support is here!

I didn't push it in at all, there wasn't any room for that - I simply filed it off together with the surrounding plastic. If you have another drive than the one in the video you can't slavishly follow the steps described there anyway - just let the head go to track 0 and mark its position, then powe...

The MAME license would be great and I'm glad you have finally agreed on something. Keep up the good work!

Re: I can't say I didn't see that coming...

I've checked that, and it's a very small portion of what the real library does. However, as I said many times we are going to publish the real source for the library - and it's been available to whomever asked for it for years. Since AFAIK, MESS has a policy of not including anything that can't be ...

Re: Far out (useless?) idea: QIC-117 ("floppy tape") support

As far as I understand, the file storage on those tapes is standardized too, in the QIC-80 standard. Basically: 1.) The tape has 28 or so linear tracks that go back and forth (i.e. every other track is written with the tape moving backwards). 2.) Data is organized into segments. Each segment consist...

Re: One-pass "flippy" disk support is here!

Darkstar, just FYI I did the mechanical part of the modification on my drive with nothing more than a file and a caliper (So you don't have to look it up: eine Feile und eine Schieblehre). Takes a bit longer but it worked just as well.

Re: Far out (useless?) idea: QIC-117 ("floppy tape") support

We still haven't such a drive, if anyone wants to donate one or two, we could take a look. Also some pre-written "disks" would be nice. I have one (a Conner drive I bought new in 1994 or 1995), which I could lend to you for as long as you like, though being the compulsive hoarder that I am, I'm not...

Re: One-pass "flippy" disk support is here!

What you suggest cannot be done as it would mean every single seek below 0 would grind the head back and forth to ensure it's at the correct position - not something you really want... Probably the best thing would be to disable CTRL-C. Of course that would quite do the trick. No, I wanted the syst...

Re: One-pass "flippy" disk support is here!

Mixing up DD and HD content is not a good idea and may or may not work. If you refer to my problems with readability on tracks in the 50s: As far as I can see, I didn't mix DD and HD content. I wrote DD IPFs to DD floppies. Yes, I did so in a HD 5.25" drive (not because I would want 5.25" Amiga dis...

Re: One-pass "flippy" disk support is here!

I've found another small problem with the negative seeking: If you send the head to a negative position, then immediately press CTRL-BREAK and repeat the dtc command before the firmware has moved the head back to track 0, the drive will try to go even further down, which (on my Mitsumi drive) rather...
